The automatic transmission assembly with reference numbers 30500-0T030 and 30500-48330 is designed for the Aisin U760E 6-speed automatic transmission. Engineered specifically for transverse front-wheel-drive layouts, this highly efficient and lightweight unit is the standard transmission for Toyota's 2.5L 4-cylinder (2AR-FE) engines in the Camry, RAV4, Avalon, and related mid-size platforms.

Complete Assembly Includes:
✅ Lightweight aluminum transmission case with optimized planetary gearsets
✅ High-efficiency torque converter with Flex Lock-up clutch
✅ Valve body with precision linear shift solenoids
✅ Integrated Transmission Control Module (TCM) or external ECU control interface
✅ Clutch packs, brake bands, and high-volume oil pump
✅ Input/Output speed sensors, range selector, and sealing gaskets
Note: Transmission mounts, shift cables, axles, and external cooler lines may need to be transferred from the original unit.
Key Features:
✅ Flex Lock-Up Technology: The torque converter lock-up clutch engages in a much wider speed range (even in 2nd gear under certain conditions), providing a direct-drive feel and significantly improving fuel economy.
✅ Compact & Lightweight: Utilizes a highly integrated gear train design, making it lighter and more compact than previous 6-speed transaxles.
✅ Smooth Shift Logic: Advanced electronic control ensures seamless gear transitions, perfectly matched to the torque curve of the 2.5L 4-cylinder engine.
✅ High Thermal Efficiency: Optimized fluid routing and cooling passages prevent overheating during sustained highway driving or light towing.
Technical Notes:
Critical Installation Requirements:
-
Fluid Specification: Must use Toyota ATF WS (World Standard) exclusively. Using incorrect fluid will ruin the friction characteristics of the Flex Lock-up clutch and cause severe shudder.
-
Fluid Level Check: Must be performed with the transmission at operating temperature (typically 70°C–80°C) and the engine idling, using the overflow check plug on the transmission pan.
-
ECU/TCM Reset: After installation, the ECU memory reset and shift adaptation learning must be performed using Toyota Techstream or equivalent diagnostic tools to ensure proper line pressure and shift timing.
-
Cooler Flushing: The transmission cooler (integrated into the radiator) and external lines must be thoroughly flushed to remove metallic debris from the failed unit.
Common Issues & Maintenance:
-
Valve Body / Solenoid Wear: High-mileage units may experience wear in the valve body sleeves or sticky solenoids, leading to harsh 2-3 shifts or flaring. Regular fluid changes prevent abrasive debris buildup.
-
Torque Converter Shudder: A vibration felt at low speeds or during light acceleration can occur if the ATF WS fluid degrades and loses its friction modifiers. A fluid exchange or torque converter replacement resolves this.
-
Fluid Service Intervals: A drain and fill every 60,000–80,000 km is strongly recommended to maintain the health of the Flex Lock-up clutch and extend the lifespan of the U760E.
